Hi Community,when updating the kernel from 4.15.0-43 to 4.15.0-45, a fatal error occurs when logging in to the text console (multi-user target, Runlevel 3). After entering the login name (eg root) plus enter key, the cursor immediately moves on from the input prompt for the password, i. it sent an empty password for login. This is wrong and not correct.

The bug also occurs with kernel 4.18.0-14, which I have installed as a trial, affecting at least two kernel versions of it 4.15.0-45 and 4.18.0-14. The error does not occur if you want to log in as root after starting the KDE desktop with the console. So the last working kernel is 4.15.0-42.

The error does not occur if you want to log in as root after starting the KDE desktop with the console. Is the error already known neon or is there a bug report about it? What can you do that the login with the above mentioned kernel versions in the text console works again?Distribution: KDE neon User Edition 5.14

Where does the text-cursor move to?Asking for account-name, again? Something else?

The cursor moves to enter the password, but jumps immediately. The error message "Login incorrect" appears four times. Then the erroneous login messages are cleared on the screen and it starts all over again.

Is there some output in the logs ("journalctl -b")?Search for "login" or "tty" or for the useraccount-nameYou did enter ("root"/<whatever>).

Do you have a grub menu and a selection of an older version of the kernel? If you do not, think it is a solution boot the system is in recovery mode, login as root and install some mainline kernel eg. 4.19 or 4.20

I can confirm I'm getting the same issue.Logging in with Plasma's user interface is working just fine.However, whenever I switch to another terminal-only screens (Ctrl+Alt+F2 and so on), after pressing ENTER after typing in my username in the username prompt, it will somehow keep on sending more ENTER to the input on a loop, so I can't type in my password since it will forcefully submit the empty password prompt.After it fails to login, it will of course show another login prompt to try again, but this time I won't even be able to input my username since it will forcefully submit the empty username prompt. And as we know it, empty username will fail too.So yeah, it will keep on doing that until the maximum 4 tries, after which the screen will just "reset", and I will end up with the same issue all over again if I try to login.

EDIT: Someone mentioned being unwilling to view the screenshot from one of the previous replies.Here it is re-uploaded somewhere else:Pretty much the same thing I'm seeing.

EDIT 2: Trying to login as root or not appears to be irrelevant, as I'm getting the issue when trying to login to my own non-root account.
